CodingGuidelines: do not ==/!= compare with 0 or '\0' or NULL
while( condition )
func (bar+1);
+ - Do not explicitly compare an integral value with constant 0 or '\0',
+ or a pointer value with constant NULL. For instance, to validate that
+ counted array <ptr, cnt> is initialized but has no elements, write:
+
+ if (!ptr || cnt)
+ BUG("empty array expected");
+
+ and not:
+
+ if (ptr == NULL || cnt != 0);
+ BUG("empty array expected");
+
- We avoid using braces unnecessarily. I.e.
if (bla) {
